Word Origin & History
heaven
O.E. heofon "home of God," earlier "sky," possibly from P.Gmc. *khemina- (cf. Low Ger. heben, O.N. himinn, Goth. himins, O.Fris. himul, Du. hemel, Ger. Himmel "heaven, sky"), from PIE base *kem-/*kam- "to cover" (cf. chemise). Plural use in sense of "sky" is probably from Ptolemaic theory of space composed of many spheres, but it was also formerly used in the same sense as the singular in Biblical language, as a translation of Heb. pl. shamayim. Heavenly "beautiful, divine" is from 1460, often (though not originally) with reference to the celestial "music of the spheres;" weakened sense of "excellent, enjoyable" is first recorded 1874.
